The rapid advancement of additive manufacturing technologies has significantly transformed numerous industries, enabling efficient and precise production of three-dimensional objects. This paper explores the field of 3D printing, with a particular focus on two prominent techniques: fused deposition modeling (FDM) and stereolithography (SLA). The aim of this research is to provide a comprehensive overview of these technologies, encompassing their operational mechanisms, key components, materials, as well as their specific characteristics and limitations. The theoretical part of the paper begins with a thorough analysis of FDM 3D printing technology. It explains the operation of FDM printers and the interplay of key components. It also explores the qualities and limitations of FDM printing, offering a comprehensive insight into its various applications. In addition to FDM technology, the paper also analyzes SLA 3D printing technology to elucidate its unique features and constraints. The paper also delves into design guidelines that are crucial for achieving excellent quality in 3D printed objects depending on the printing technology. The practical part of the paper highlights the creative aspect of 3D printing. It explains how Blender and digital sculpting techniques are used to create 3D models using polygonal modeling and digital sculpting techniques. The practical section of the paper includes the application of acquired knowledge in real-life situations. The creation of a character and subsequent 3D printing demonstrate the integration of theoretical understanding and practical skills.
